Sacrifice

Never sacrifice a white cock, was one of the doctrines of
Pythagoras, because it was sacred to the moon. The Greeks went further,
and said, “Nourish a cock, but sacrifice it not,” for all cockerels
were sacred either to the sun or moon, as they announced the hours. The
cock was sacred also to the goddess of wisdom, and to Esculapios, the
god of health; it therefore represented time, wisdom, and health, none of which are ever to be sacrificed. (See Iamblichus Protreptics, symbol xviii.)
